<p>PROBLEM TO BE SOLVED: To precisely press in a pile by efficiently and readily fixing the pile in the foundation.SOLUTION: In a gap 103 between the foundation 100 and a pile 101 installed in the foundation, a plate spring 10 generating elastic force in a direction of expanding the gap is installed and fixed. Additionally, two plates 31, 32 inserted in the gap are relatively slid on respective tapered faces so as to be expanded in the width direction, and are then fixed (Fig. 5). The fixed pile is grabbed as a reaction pile by a pile press-in machine, which in turn presses in another pile.</p> |
